Triggering of Measurements
Measurement States
The following examples describe states of the test set under various conditions. Refer to Figure 20. on page
219.
Example 18. Inactive State
If the test set has just been powered on, or any form of preset has been performed, then the measurement state
is inactive.
Example 19. Wait for Trigger State
If a measurement has been initiated with the INITiate command but has not been triggered, or a
measurement has been selected from the Measurement Selection menu but has not been triggered, then the
measurement state is wait for trigger.
Example 20. Measuring and Idle States (Trigger Arm Single)
If the trigger arm is set to single, the trigger source is available, and the trigger qualifier (optional) is satisfied,
the measurement state transitions to measuring and measurement results are now available to the user. After
results are available, the state transitions to idle (awaiting another INITiate).
Example 21. Measuring State (Trigger Arm Continuous)
If the trigger arm is set to continuous, the trigger source is available, and the trigger qualifier (optional) is
satisfied, the measurement state transitions to measuring and measurement results are now available to the
user. The measurement is continually triggered until the measurement is deactivated. When the
measurement is deactivated (INITiate:<MEAS>:OFF. or Close Measurement), it becomes inactive.
Trigger Arm (Single or Continuous) Description
Trigger arm determines if a measurement will make one measurement then return to idle (single), or
automatically rearm on completion of a measurement and repeat the process (continuous).
NOTE When operating the test set remotely, trigger arm must be set to single, this causes the
measurement cycle to transition to the idle state but remain active.
Pressing the Start Single key on the front panel will cause all currently active measurements with trigger arm
set to single to arm and make the measurement.
Pressing Shift, Start Single (Stop) causes all measurements with trigger arm set to single to abort the
measurement.
It is unnecessary to arm a measurement if trigger arm is set to continuous it will continue to cycle in the
measuring state.
